Latest Patents

Kiyohide Tatsumi's latest patents showcase his expertise in circuit board technology. One of his notable inventions is a method for creating a high-quality circuit board. This process involves disposing of metallic foils on either surface of a prepreg sheet of low compressibility, which contains conducting holes filled with conductive paste. The prepreg sheet is then compressed at a relatively low temperature, followed by raising the temperature under pressure, causing the resin to melt and harden. This innovative approach ensures the stabilization of connecting resistance, resulting in superior circuit board quality.

His second recent patent focuses on developing a circuit-formed substrate and a method for its production. This invention provides a circuit board with reliable electrical connections. It features an insulated board material that includes connections for inter-layer connectivity and a reinforcing member. The thickness of the entire insulated board material is designed to be at least equal to and not more than 1.5 times that of the reinforcing member, ensuring strength and stability in electronic applications.
